A fat conditioning apparatus includes a conditioning vessel enclosing a conditioning chamber and a displacable plug. The conditioning chamber is bounded on one end by the displacable plug and has a variable volume that is a function of the position of the plug within the conditioning vessel. The apparatus has utility in a fat conditioning method, wherein the conditioning chamber contains a harvested fat emulsion. A washing liquid is injected into the conditioning chamber and mixes with the harvested fat emulsion, thereby displacing the plug in an outward expansion direction and expanding the variable volume of the conditioning chamber. The resulting mixture of harvested fat emulsion and washing liquid is stratified in the conditioning chamber into a contaminant-lean fat fraction and a contaminant-rich remainder fraction. The fat fraction, which is substantially free of the remainder fraction, is recovered from the conditioning chamber as a desired product of the method.

A method of treating a reservoir fluid mixture including an oleaginous component and an aqueous component includes contacting the reservoir fluid mixture with an interface destabilizing composition. The interface destabilizing composition comprises a biochelant and a solvent. A method of servicing a wellbore includes flowing a reservoir fluid to a vessel. The reservoir fluid comprises an oleaginous component and an aqueous component. The method also includes introducing into the vessel an interface destabilizing composition comprising a biochelant and a solvent. The vessel comprises a gun barrel or wash tank separator. In addition, the method includes recovering at least a portion of the oleaginous component from the vessel.

Disclosed herein is a novel class of multiple charged cationic or anionic compounds that are derived from an aza-Michael Addition reaction between a polyamine (Michael donor) and an activated olefin (Michael acceptor), methods of making the same, and use thereof. Also disclosed herein are the methods of using multiple charged cationic or anionic compounds disclosed herein in a reverse emulsion breaker composition to break reverse emulsion commonly found in a produced fluid in oil and gas operations. The disclosed REB methods or compositions are found to be more effective than those methods or compositions including commonly used for oil/solid and water separation.

Compositions for water treatment are provided. In some embodiments, the composition comprises: a cationic polyacrylamide-type polymer having a charge density of about 10% to about 40% and a molecular weight of about 600×10.sup.4 g/gmol to about 900×10.sup.4 g/gmol; and a cationic surfactant, the surfactant comprising an alkyl quaternary ammonium salt. Also provided are related methods and kits for treating wastewater with dispersed and dissolved organic matters and oils. Embodiments of the compositions, methods, and kits can be used to treat oil-in-water emulsions, produced water, and process water containing dispersed and/or dissolved organic matter such as hydrocarbons from various process industries including Steam Assisted Gravity Drainage (SAGD) oil operations.

An oil purification filter for purifying a contaminated oil includes a filter body having a first portion and a second portion, where at least the first portion is impregnated with a separation aid. The separation aid is substantially insoluble in the contaminated oil because of its polar properties, and the separation aid is configured to adsorb/absorb contaminating solids or dissolved impurities in the contaminated oil by chemical interactions. The filter body may comprise one or more sheets of cellulose fibers.

A method of reducing injection pressure during a hydrocarbon resource recovery operation, the method comprising: introducing a treatment fluid comprising a biochelant and a solvent for a time period sufficient to reduce an injection pressure of the injection well by equal to or greater than about 25%. A method of asphaltene and paraffin dispersion, the method comprising introducing a treatment fluid into a well disposed within a subterranean formation, wherein the treatment fluid comprises a biochelant and solvent.
